; This file contains tests that should have identical output for the ilp32,
; ilp32f, and ilp32d ABIs. i.e. where no arguments are passed according to
; the floating point ABI. As well as calling convention details, we check that
; ra and fp are consistently stored to fp-4 and fp-8.

; Check that on RV32, i64 is passed in a pair of registers. Unlike
; the convention for varargs, this need not be an aligned pair.
